Regarding your first examples, I think the two versions have different meanings; adjective, modified noun. I think a similar bad marriage is "Please stay for awhile", also - lamentably - much seen recently. As to 'worldview, I've always used a single word, but I see the OED has it hyphenated.

If you are a member of The National Association of Realtors, you are a Realtor, with a capital R. If not a member, I suppose you can be a realtor. I read it without the capital often. It could be a trade marked word which, due to constant use, has lost its capital letter status. Cf: Coke - coke.

More on 'anymore'. There's a good reason it ought to be two words. The 'any' in compounds like 'anything' and 'anywhere', et cet does not have the same meaning as the 'any' in 'any more'. Also, the pronunciation doesn't match, I mean of the placement of the accent.

anymore vs. any moreAlthough both anymore and any more are found in written use, in current writing anymore is the more common styling. Anymore is regularly used in negative⟨ No one can be natural anymore. —May Sarton ⟩, interrogative Do you read much anymore? , and conditional If you do that anymore, I'll leave. contexts and in certain positive constructions.⟨ The Washingtonian is too sophisticated to believe anymore in solutions. —Russell Baker ⟩In many regions of the U.S. the use of anymore in sense 2 [anymore = at the present time, these days] is quite common in positive constructions, especially in speech.⟨ … everybody's cool anymore. —Bill White ⟩⟨ Every time we leave the house anymore, I play a game called "Stump the Housebreaker." —Erma Bombeck ⟩The positive use appears to have been of Midland origin, but it is now reported to be widespread in all speech areas of the U.S. except New England.

In my opinion, anymore as one word is usually appropriate.However, I can imagine a situation where two words would be appropriate:A (in a shop): Do you have any apples?B (shopkeeper): I have three here. Just a minute, let me look in the back to see if there are any more there.

And I'd like to hear more from speakers of the positive anymore dialect.

Thank you for your scholarship. My objection to 'anymore' is twofold. For one thing, the pronunciation is not in accord with the typical compound: 'anything', 'anyone', etc. But primarily, the meaning of 'any' is different, if subtly.
